"Guided tour" can mean more than one thing…read more
It can mean, "We're going to ferry you into the jungle in comfort, sharing interesting bits of history and descriptions of the local culture with you while you sip water and enjoy the scenery."
In this case, it meant, "We'll give you the keys to a car (a stick, which luckily, I can drive) then one of our guides will drive ahead while you follow him, and you'll stop along the way so people can show you how they make stuff, then you'll be pressed to buy their stuff."
Ah, well.
I don't mind being pitched, as I have no trouble saying, "No, gracias." Plus there was a lady making hats that were very cool, though my wife muttered, "No" as we walked up, reading my mind as I started picking out my new hat.
The problem with this "adventure" was that I didn't think through the situation: if I was driving, I wouldn't be able to see anything but dust flying up from the guide's car ahead of me.
But it could have been worse. Imagine if I'd ignored my wife's comment and bought a hat?
